Answer:
x = -52
Step-by-step explanation:
1/3x-2/3=-18
Multiply each side by 3 to clear the fractions
3(1/3x-2/3)=-18*3
x - 2 = -54
Add 2 to each side
x-2+2 = -54+2
x = -52
 
        
                    
             
        
        
        
Answer:
14 minutes below or 6 minutes above
Step-by-step explanation:
Let's say Sophia's time was 10 minutes WORSE

Answer:
y=6
Step-by-step explanation:
(2y-3)*2=4y-6
You multiply by two because there are two sides that are considered the length
y+1*2=2y+2
Same thing here
4y-6+2y+2=32
6y-4=32
 +4. +4
6y=36
 /6 /6
y=6
